What do you call a person who studies vampires and werewolves?

The majority of the time, a person studying these fields is known as a Parapsychologist, although I tend to disagree with this title if the person is a believer in such supernatural beings. Generally a person who studies vampires, or vampirology, is known as a vampirologist. The same goes for the study of werewolves, yet I'm thinking there would be something else out there associated with the latin roots for the Word 'werewolves.'
